Description

Ash discharging device of explosion-proof dust remover

Technical Field

The utility model belongs to the technical field of remove dust, especially, relate to an explosion-proof dust remover unloads grey device.

Background

The dust remover is equipment equipped in many production industries, and has the function of collecting and removing dust at a dust raising position, so that the dust amount discharged into the atmosphere is reduced, and the dust remover is important environment-friendly equipment for improving environmental pollution and air quality. The mixture of combustible dust and air in the dust removal device can explode in the explosive range, such as when ignited or when encountering an ignition source. The deposited dust becomes an ignition source for initiating explosion if spontaneous combustion is carried out after the deposited dust is heated, and primary explosion is caused; the primary explosion impacts the dust layer to form dust cloud, which causes secondary explosion of dust. Dust explosion will cause safety accident problem and economic loss to production, so an explosion-proof dust remover is needed for removing explosive dust. Unload grey device and connect the dust remover inside and outside, be the core of explosion-proof dust remover explosion-proof performance, present explosion-proof dust remover unloads grey device and adopts under the ash bucket direct mount star type tripper more, do not export the whole outputs of the inside ash of ash bucket during defeated ash, adopt the isolated outside air of ash in the ash bucket to get into the ash bucket, but star type tripper sealing performance is poor, if unload grey improper, cause grey performance to weaken, there is the explosion hazard, the ash in the ash bucket exists in the ash bucket for a long time in addition, cause to harden easily, cause and unload grey difficulty.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model discloses an explosion-proof dust remover unloads grey device, simple structure, it is sealed effectual, can in time arrange middle ash storehouse with the ash in the ash bucket, prevent that the ash in the ash bucket from hardening.

In order to achieve the technical purpose, the utility model adopts the following technical scheme:

an ash discharging device of an explosion-proof dust remover comprises an ash hopper, an upper gate valve, a middle ash bin and a lower gate valve, wherein the upper gate valve is fixed between the ash hopper and the middle ash bin through an upper flange and a lower flange; the intermediate ash bin is provided with an ash conveying gas inlet and an ash conveying gas outlet.

Further, the upper gate valve and the lower gate valve are double-plate pneumatic gate valves or electric gate valves.

Furthermore, the first vibrator and the second vibrator are arranged on opposite sides of the middle part of the ash hopper.

Furthermore, a gas distribution plate is arranged on the inner side of the ash conveying gas inlet.

Furthermore, a dust filter screen is arranged on the outer side of the ash conveying gas outlet.

The utility model discloses an explosion-proof dust remover ash discharging device, dust that the dust remover was collected and is got off get into the ash bucket, go up the charge level indicator and detect the ash level, when reacing the setting value, go up the push-pull valve and open, the electromagnetic shaker is opened, and the dust gets into middle ash storehouse, lets in compressed gas by compressed gas blowout mouth and sweeps, goes up the push-pull valve after the ash evacuation in the ash bucket and closes, and the push-pull valve is opened down, lets in gas by defeated ash gas entry under the gas pressure effect, and the ash in middle ash storehouse is discharged. The upper gate valve and the lower gate valve are opened and closed alternately, so that the sealing in the ash bucket can be ensured, and the explosion of the dust remover caused by air entering the ash bucket is prevented.
